A Slovak company signs a five-year office lease in Warsaw. The contract runs to 47 pages. Rent indexation, service charge caps, break clauses, reinstatement obligations – each clause carries financial exposure that only becomes visible when something goes wrong. By that point, renegotiation is rarely an option.
Slovak tenants leasing office space in Poland face a legal framework that differs materially from Slovak civil law. Polish commercial lease terms are governed by the Kodeks cywilny (Civil Code, KC) and supplemented by market-standard BOMA or GLA measurement conventions. Lease agreements in Warsaw's central business district routinely exceed PLN 500,000 in annual rent, placing significant financial risk on tenants who sign without independent legal review. Three areas demand immediate attention: indexation mechanics, service charge audit rights, and reinstatement liability.
This alert identifies the clauses that most frequently generate disputes, explains the Polish legal context for each, and sets out concrete action items for Slovak tenants currently negotiating or holding an existing office lease in Poland.
What makes Polish office leases different for Slovak tenants?
Polish law gives landlords considerable freedom to draft lease terms. The Civil Code sets a baseline, but most obligations – maintenance responsibilities, subletting rights, fit-out approval – are contractually defined. Slovak tenants accustomed to more prescriptive domestic legislation often underestimate how much the written contract controls. A clause that would be void under Slovak law may be fully enforceable in Poland.
Measurement standards create an immediate mismatch. Polish landlords commonly apply BOMA or their own building-specific gross leasable area (GLA) definitions. The rentable area stated in the lease can exceed the area a tenant actually occupies by 10–18%. This difference compounds over a five-year term. On a 500 sqm lease at PLN 120 per sqm per month, an 18% loading adds roughly PLN 1.3m in rent over five years – paid for space the tenant never uses.
The National Court Register (KRS) governs the legal standing of Polish landlord entities. Slovak tenants should verify the landlord's KRS entry before signing. A mismatch between the signatory's authority and the KRS representation rules can render the lease voidable. The Polish Financial Supervision Authority (KNF) is relevant where the landlord is a real estate investment fund subject to regulated disclosure obligations.
- Confirm measurement methodology and request an independent survey
- Verify landlord's KRS entry and signatory authority
- Check whether the building is encumbered by a mortgage or pledge
- Identify which court has jurisdiction for disputes
Slovak tenants with existing leases should also review whether their agreement was registered with the relevant land registry (księga wieczysta, perpetual book). Registration protects the tenant's rights against a new owner if the property is sold. Without it, a buyer acquiring the building takes free of the lease in certain circumstances – a risk that materialises without warning.
Which lease clauses carry the highest financial risk?
Three clause types generate the majority of office lease disputes in Poland. Each carries a distinct financial profile and a different legal remedy. Slovak tenants should map their exposure across all three before the lease is signed – or, if the lease is already running, before the next break option window closes.
Rent indexation is the first pressure point. Most Warsaw office leases index rent annually to the Eurozone Harmonised Index of Consumer Prices (HICP). During 2022–2023, HICP indexation produced increases of 8–11% per year. A tenant on a PLN 80,000 monthly rent faced an additional PLN 96,000 in annual cost from a single indexation cycle. Caps on indexation are negotiable at heads-of-terms stage but rarely offered spontaneously by landlords. Once the lease is signed, the cap is gone.
Service charge structures are the second risk area. Polish leases typically allow landlords to pass through building operating costs with limited audit rights for tenants. Charges covering property management, insurance, and common area maintenance can represent 20–30% of headline rent. The lease should specify a reconciliation deadline – 90 days after year-end is market standard – and grant the tenant the right to inspect supporting invoices. Without an explicit audit right, tenants have limited recourse before the District Court (Sąd Okręgowy).
Reinstatement obligations are the third and most underestimated exposure. Polish leases frequently require tenants to restore premises to their original condition at lease end. For a fit-out costing PLN 2m, reinstatement can cost a further PLN 400,000–600,000. This obligation is often buried in a single clause and rarely discussed during negotiation. A tenant who misses it faces a demand on the last day of the lease, with no time to plan.
We secured a reduction of a disputed service charge reconciliation exceeding PLN 800,000 for a technology-sector tenant in the Mazowieckie region (spring 2025). The landlord had applied a cost allocation methodology not disclosed in the lease. Identifying that gap required a line-by-line review of the original contract.
What should Slovak tenants do immediately?
Action depends on where the tenant sits in the lease lifecycle. Pre-signature, the window for negotiation is open. Post-signature, the focus shifts to monitoring and enforcement. In both cases, a structured review conducted within a defined timeline prevents the most costly outcomes.
For tenants currently negotiating, the critical deadline is heads-of-terms. Once heads are agreed, landlords treat commercial terms as settled. Legal review at this stage typically costs PLN 8,000–15,000 and can recover multiples of that figure through negotiated caps, improved audit rights, and reinstatement carve-outs. Slovak companies expanding into Poland should also review our guide on buying property in Poland as a Czech Republic national, which addresses related property law concepts applicable across the region.
For tenants already holding a lease, three actions are time-sensitive. First, locate the break option clause and calculate the notice deadline. Most Polish office leases require 6–12 months' written notice to activate a break. Missing the window by one day forfeits the right entirely – an irreversible consequence with no judicial remedy. Second, request the most recent service charge reconciliation and verify it against the lease's cost categories. Third, identify any fit-out works completed during the tenancy and assess reinstatement exposure before the lease end date.
- Map all notice deadlines and enter them in a monitored calendar
- Obtain the current service charge reconciliation statement
- Assess reinstatement obligations against actual fit-out works
- Confirm lease registration status in the perpetual book
- Review dispute resolution clause and applicable law
Slovak tenants operating across multiple jurisdictions should note that Polish lease disputes are resolved before Polish courts unless the parties have agreed to arbitration. The choice-of-law clause matters.

We obtained a full waiver of reinstatement liability valued at PLN 550,000 for a Slovak logistics company with premises in Lower Silesia (autumn 2024). The reinstatement clause contained an ambiguity that, properly argued before the landlord's legal team, supported a negotiated release without litigation.
Specific lease terms create personal exposure for Slovak company directors who sign guarantees. Polish landlords regularly request personal or parent-company guarantees covering 6–12 months' rent. A guarantee signed without understanding its scope can trigger personal liability for the full outstanding lease term – a risk that persists even after the company exits Poland.

Frequently asked questions
Q: Can a Slovak tenant challenge a rent indexation clause after the lease is signed?
A: Challenging indexation post-signature is difficult. Polish courts generally enforce freely negotiated commercial terms between professional parties. The strongest remedy is negotiation at heads-of-terms stage, where a cap of 3–5% per annum is achievable in most Warsaw submarkets. Once the lease is executed, the tenant's options are limited to renegotiation on renewal or at a break point.
Q: How long does a service charge audit typically take?
A: A structured audit of one year's service charge reconciliation takes 4–8 weeks, depending on the landlord's responsiveness. The lease should specify a response deadline of no more than 30 days for document production. Tenants who initiate audits within 90 days of receiving the reconciliation statement are in the strongest procedural position. Delays beyond that window can be used by landlords to argue waiver.
Q: Is it a common misconception that Polish leases automatically protect tenants against building sale?
A: Yes. Many tenants assume that a signed lease survives a change of ownership automatically. Under Polish property law, this protection applies only if the lease is registered in the perpetual book (księga wieczysta) or if the buyer had actual knowledge of the lease. Unregistered leases carry real risk of termination by a new owner on 3 months' notice in certain circumstances. Registration costs are modest – typically PLN 200 in court fees – and should be completed within 30 days of signing.
